Meng Wanzhou, the company's finance director, was arrested in Vancouver on December 1. Details of the arrest were not published, but the United States is investigating Huawei for possible violations of sanctions against Iran.
The capture in Canada, Meng Wanzhou, the daughter of the founder of the Chinese telecom giant Huawei and the company's financial director, triggered a political storm between Washington and Beijing.
Although the accusations against Wanzhou were not originally reported, it was found that the arrest was made at the request of the United States, which considers that the company has violated sanctions against Iran.
China demanded the immediate release of the executive and called for the detention to be "a violation of human rights".
Huawei, which, with 15% of the world's market, is the second-largest mobile phone maker in the world, was banned in several Western countries because they fear that Beijing will force the company to disclose industrial secrets and other confidential information which could jeopardize national security.
Countries, such as the United States, New Zealand and Australia, have been blocking the giant for security reasons. While others, such as Canada, Germany, Japan and South Korea, the company assessed.
Huawei, on the other hand, defends its independence, rejects allegations and insists that it is a private company.
Is Huawei a threat to national security?
The United States argues that Huawei poses a risk to national security.
And Washington explains it to its founder's links with the army (Ren Zhengfei is a former official of the People's Liberation Army of China) and because of its growing importance on the global level.
Huawei is rapidly evolving in the equipment market for cellular networks. It's right now the world's largest provider of telecommunications equipment.
Like China, it occupies an increasingly important place on the world stage, this also happens to a technological giant.
Theoretically, it has control of the technology, which is at the heart of the most important communications networks, the company the ability to escape or interfere communication in a potential conflict, especially in a context in which more and more products work over the Internet.
The United States is particularly concerned about the rule adopted by the Chinese National Intelligence Agency in 2017, stating that companies must "support, cooperate and participate in national intelligence."
After the approval of this Regulation, USA, Australia and New Zealand it was forbidden for local businesses to use Huawei to provide technology that makes it possible to use 5G networks.
There are three members of the group who are sharing intelligence "5 eyes". The fourth group is Canada, which is currently studying the relationship with society.
And the United Kingdom has so far not decided against the company even though it has asked it to resolve the problems that present "new risks" for the network.
What does Huawei say?
The company is presented as a private company, whose owners are its employees and has no ties to the Chinese government, which exceeds the tax liability.
Huawei says that one of its priorities is the protection of its products and that this part of the hostility it suffered is due to the fact that the company is treated as a threat from a commercial point of view.
In the past, the Chinese government itself stated that the blocking of Huawei products is due to "protectionist and discriminatory practices".
A new episode of hostility to the company comes during the commercial war between Washington and Beijing, with President Donald Trump accusing China of unfair business practices and facilitating theft of intellectual property American companies.
On the other hand, as several countries intend to introduce 5G communication networks at the same time, the scenario has become more competitive for companies seeking to obtain contracts.
"There is a military norm" for scenes, says Emily Taylor from the UK study center Chatham House.
"I think that the commercial advantage of setting standards that favors your local technology providers is also something that is at risk."
